People cope with stigma via individualistic strategies that minimize stigmatized attributes, and collective strategies that positively redefine stigmatized traits. Guided by social identity theory, we surveyed people with hidden and visible disabilities to investigate the association between disability identification and strategy use. Further, we tested the prediction that self-esteem (collective and personal) varies by disability identification and strategy use. Across two surveys of adults with disabilities (Ns = 93 and 268), disability identification predicted greater use of collective strategies, and higher collective and personal self-esteem, controlling for visibility and proportion of lifetime with disability. These findings support the prediction from social identity theory that group identification may be self-protective. Findings also support the sociopolitical model within disability studies, providing theory-based empirical evidence that working for social change empowers both one's group and oneself.
